This company and its employees are true professionals. I found myself in a bad position with a cooling system failure August 2018 in Kennesaw. Under the guidance and leadership of Bob Best, they found me a prompt and affordable solution. They are highly recommended.

I have complete confidence in D. McKeon. They are completely honest, and I feel their advice is sound. They have helped me tremendously since I moved to Marietta, GA, three and a half years ago, and their technicians are wonderful and very thorough.

I own a daycare center in Kennesaw, and can not say enough good things about D. McKeon's team. I have 5 units, and over the years I believe that I have had every service tech they have out to my center, and I have met all of the ladies in the office as well stopping by to make payments and different things. Every single person that I have met from there has been consistently helpful, informative and polite. Their prices have always been fair, and everyone from the top down has given honest advice and even steered me away from services that they offer and could have tacked on, that were not necessary. They have been really great with scheduling too, since we are a childcare facility. Again, I can not rate this company and their people highly enough. Even when I mentioned them at the parts store, the guys there have nothing but nice things to say about them. A good name is one of the hardest things in the world to keep and the easiest to lose, and they are doing a great job keeping their name in good standing.

Fantastic experience working with D. McKeon's team. Bob Best was patient in answering all questions, offering his vast knowledge and experience, and personally oversaw the installation of two new HVAC systems tailored to our needs, preferences, and budget. The other members of the installation team, Bob and Kevin, were very professional and performed quality work. Despite facing the stressful scenario of replacing two 25 year old HVAC systems, we were fortunate to choose this company for the job.

D McKeon recently replaced a 5 ton HVAC system in our home. After securing two other bids for this work I found McKeon's to be very competitive. Their team completed the work on time and in a very professional manner. I would highly recommend them for any HVAC work.

I would recommend this company highly. I called because our furnace went out and within 3 hours they were there to diagnose the problem. I needed a new furnace (mine was over 30 years old) and they installed a new furnace the next day. Excellent service and would highly recommend you to choose them as your heating and air service people.

This company is very professional. Focused on great customer service. They are knowledgeable and keep abreast of technology changes. The very best vendor I have ever had for my small business. You are set for your Hvac upkeep if you hire them to take care of it.

We have been clients of D. McKeon for many years. Ever since did our first furnace replacement with them and saved money long term by installing a unit with lower BTU and a 2 stage Blower. We have been in our home for 37 years,, upgraded both of our systems twice and redone our upstairs duct work. All this work has been with D. McKeon

Very friendly office personnel; techs are competent, do not do extra unneeded work & explain (if you are available) what was done, etc.; you know in advance when tech is supposed to be there and are alerted when he is on the way; reasonable charge.

I was looking for parts for my AC unit. Every place that I searched denied me selling the part and charging me over $250.00.Called D. Mckeon Inc. and the staff was very helpful and courteous. Got the part I needed way below.Thanks.
